What is the battery model for BMW remote control?

[LaRowan]

The battery model for BMW remote control is CR2032, which is a button cell. Most models of remote key batteries use CR2032. The advantages of using this lithium button battery are its small size and long lifespan, typically lasting more than 3 years. The BMW 525 is a high-end 4-door, 5-seat sedan under the BMW brand, with body dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, and a wheelbase of 3105mm. It is equipped with an 8-speed automatic transmission. The BMW 525 is powered by a 2.0T turbocharged engine, with a maximum power output of 135 kW and a maximum torque of 290 Nm.

I've been driving a BMW for several years, and the remote key battery is usually a CR2032 coin cell. I've replaced it several times, and it's not difficult to do: first, unscrew the small screw on the back cover of the key—a flathead screwdriver will do—then pop out the old battery and replace it with a new CR2032. Be careful not to insert it the wrong way; the positive side should face up. The battery lasts about two to three years, and replacing it early can avoid the awkward situation of suddenly being unable to unlock the car door. Last week, I encountered this issue once, but luckily, I had a spare battery in the car and replaced it right away. Buying one online or at an auto parts store is very cheap, about 10 yuan each. Avoid using off-brand batteries; stick to original or high-quality ones to prevent leakage. If the remote feels sluggish, check the battery life promptly.

I just replaced the battery in my BMW key a few days ago—it's that small round CR2032 type. The process is incredibly simple: open the key, take out the old battery, pop in a new one, and snap it back together. The battery cost is minimal, easily available at supermarkets or online. It lasts about three years before needing replacement. Last time, I forgot, and couldn’t lock the car after parking—luckily, a roadside shop saved the day. Now, I always keep a spare CR2032 in the glove box, just in case. When replacing, handle it gently to avoid breaking the clips. Keep the battery compartment clean, as dust can affect contact. This battery model fits most BMWs, like older 3 Series or newer X5 models. Don’t worry—it’s easy enough for beginners to try.

The common remote battery for BMW is CR2032, and my buddy's car uses the same one. Replacement is super easy: just pry open the key cover, swap the battery, and make sure not to insert it backwards. When buying CR2032, watch out for anti-counterfeit labels—fake ones can damage the key. Generally, it needs replacement every two years, hassle-free and cost-effective. There are plenty of online tutorials; just follow a video and you're done in 5 minutes. Once encountered a dead battery that locked me out, but thankfully the phone app could start the car in an emergency. Keep a spare battery in your backpack for convenience. Newer models might differ slightly, but CR2032 is universally compatible.
